BACKGROUNDS: Sexually transmitted disease is class 3 major communicable disease group in Korea, and nationwide surveillance is required to control it. It is necessary to investigate the trends and current characteristics of STDs for effective control. METHODS: We analysed the laboratory data of those who visited a health center in Seoul for venereal disease examination and had abnormal results from Jan 1, 1991 to Dec 31, 1994. Venereal disease examination was composed of serum VDRL(quantitative), Gram staining and culture of urine or urethral discharge. RESULTS: There were 1196 male cases(97.6%) among the total 1226 cases. Mean age was 31.1+/-8.4, and the most common age group was 25-34 yr-old(60.8%). Diagnosis was as follows : syphilis 48 cases(3.9%), gonorrhea 388 cases(31.6%), Nongonoccocal urethritis 773 cases(63.1%), others 10 cases(0.8%), mixed infection of syphilis and gonorrhea 2 cases(0.2 %), mixed infection of syphilis and NGU 5 cases(0.4%). The proportion of PPNG among gonorrhea was as follows : 1991 48.1%, 1992 38.0%, 1993 32.9%, 1994 58.8%. The fraction of NGU among whole urethritis patients increased year by year, 1991 68.0%, 1992 69.4%, 1993 73.3%, 1994 55.3%. There were more WBCs on Gram staining of gonorrhea cases than NGU cases(p<0.01). CONCLUSIONS: The STD patients among beneficiaries of a health center were mainly young male. Common diagnosis was as follows, NGU, gonorrhea, syphilis. The proportion of PPNG among gonorrhea decreased initially, then increased in 1994, and the fraction of NGU among whole urethritis cases increased initially, then increased in 1994.

BACKGROUND: This study aimed to investigate the practice effect of the 6-minute walk test (6MWT) after providing the subjects with knowledge of the results (KR). METHODS: Sixteen subjects with post-stroke hemiparesis volunteered to participate in this study. The 6MWT was performed by having the subjects take repeated walks along a 20-m walkway for 6 minutes; and the maximum distance walked was recorded. Two trials of the 6MWT were conducted under three conditions: no-KR, immediate-KR (providing knowledge of the time taken to complete each 20-m distance), and summary-KR (providing knowledge of the time taken to complete 60 m). RESULTS: The practice effects of all 3 conditions were determined by using the paired t-test, intraclass correlation coefficient (ICC) with <0.75, and the Bland-Altman plot. The findings of the paired t-test showed a significant difference under the immediate-KR condition only; however, no significant differences were noted under the no-KR and summary-KR conditions. In a data agreement analysis across the two trials using the ICC, none of the obtained values under the three conditions were in an acceptable range indicative of a practice effect. In the Bland-Altman plot, a greater data variation was observed under the immediate-KR condition than under the other two conditions. When comparing the conditions, the immediate-KR condition differed significantly from the no-KR condition. CONCLUSIONS: Our findings do not support the presence of a practice effect across the 6MWT. However, a practice effect seems to be clinically possible when the immediate-KR condition is incorporated into this test.

Among the skeletal tuberculous spondylitis is high incidence and curable disease, if early diagnosis and treatment are possible. We reviewed clinical manifestations and radiologic analysis of 30 cases tuberculous spondylitis from May 1983 to Sept. 1986, at Yeungnam medical center, Yeungnam University. The results were follows: 1. The frequent involve sites were thoracolumbar vertebra. 2. The continuous lesion is 86.7% of the all cases. 3. The most common type was intervertebral type, and lytic and sclerotic lesion were same incidence. 4. Paravertebral abscess, kyphosis and disc space narrowing were demonstrated more than 80.0% of the cases. 5. Computed tomography was more accurate diagnostic method rather than conventional plain study to evaluation of extent of lesion, involvement of spinal canal and cord, and size and location of paravertebral abscess. And CT guided abscess drainage procedure was helpful to diagnosis and treatment. 6. Ultrasonography was helpful to differential diagnosis between paravertebral abscess and other solid mass, and useful to follow up study of paravertebral abscess after treatment.

Surface topography of the Anisakis type I 3rd stage larva (L3), the main pathogen of anisakiasis, was observed by scanning electron microscope under magnifications of 400 to 14000X. The head bears a trapezoid undivided lip mass, with 2 mammillary elevations at the middle of the two lateral sides and a cuticular boring tooth on its ventral side. The mouth leading into the esophagus is situated in the centre of the centrally located cuticular elevation of the lip mass. The excretory pore opens ventrally just behind the boring tooth. The surface of the lip mass shows fine striations, but looks smooth elsewhere. Neither flat papillae nor minute "teeth" or "hairs" described hither to have been observed. The cuticle of the body surface shows shallow and irregular annular grooves and folds and numerous fine longitudinal micro-furrows and cristae. These surface markings appear uniformly from head to tail and to the utmost end of the pagoda like mucrones at the tip of the tail. The ventrally located crescent anus is situated about 90?m from the base of the mucron.
